I can give you some places to dig.
Dr. Nicholas Gonalez protocol - he mysteriously died a few years. He had many patients that survived liver and pancreatic cancer. There are Youtube videos out there interviewing him.
Dr. Johanna Budwig - Budwig Protocol - nominated for 7 Nobel prizes - started quantum biology - was a physicist, pharmacologist and even went to medical school for a while. When she discovered the importance of flaxseed oil and sulphur proteins to the cell membrane, she and other scientists thought this would cause a lot of cancer research but it was crickets. She treated patients up until her death in 2001 /2002 at 92. Over half of her patients were either physicians or family of phyisicians with people coming from all over the world. Dr. Om Verma has a book on Amazon and a Facebook community on the Budwig protocol. Lothar Hirneise worked with her the last couple of years of her life and runs a clinic in Germany. Watch some of his videos of Youtube.He has a book out also and is also part of the Facebook community with Dr. Verma.
If you have energy issues, the Budwig cream is incredible in making you feel better. There is a yahoo group called FlaxseedOil2 on yahoo with many memebers. They deal with the Budwig protocol also. A little difference in opinion on how Budwig is made. Lothar Hirneise does it just like Dr. Budwig did. Until he came out a few years ago and really started educating people, most of the English speaking world had just read her 3 books that had been translated from German into English and used those. The FlaxseedOil2 group came out of the study of her books.
Dr. John F. Prudden (1920-1998) - Bovine Tracheal Cartilage Products - Dr. Kaayla Daniel was doing a book with him when he passed away and it was never published. She included information from that in her book Nourishing Broth.Dr. Prudden’s full dose was always 12 capsules per day, and he said people should not expect to see results until being on the cartilage for at least 4 months. Kaayla Daniel produces it under the name Vital Proteins. She wished it was cheaper but said there’s just no way to manufacture them inexpensively.
Ketogenic diet - there has been some good results but no long term evidence of this diet where cancer is concerned. It does not mean it does not work just that it has not been around a long time. - Budwig has been around for 50 years.
Gerson has been around for a long time but I have not had time to really delve into it other than know there was lots of juices.
Drop any sugar and lower your carbohydrate intake in your diet like another anon said. good nourishing food is important to your cells.
Emotional Freedom Technique (EFT) to deal with the emotional aspects of your life. It is a mixture of acupressure and affirmations. Brad Yates does some good EFT videos.
Dr. Michael Greger - has pointed out a lot of excellent research on the some of the best fruits and vegetables to eat in fighting cancer and what types are best based on your type of cancer.
As a previous anon said you need to take care of your liver. If you have a fatty liver, lemon juice and apple cider vinegar are good for it lemon juice as well as super enzymes taken in between meals.
